Hello,

I added an issue on Github that I discovered in 15.0.0RC1: [Github] Piwigo issue #2239 . It seems that the new PDF preview feature greps through any image you try to view for PDF page markers. If an image happens to be a large video for example, you run out of PHP parser heap in the process. I've made a PR of a fix proposal.

There's not traffic on the Github issue or the PR, but I would like to have it fixed before 15.0 release, so I opened a thread here.
